/ip firewall nat

add chain=srcnat out-interface=ISP1 action=masquerade
add chain=srcnat out-interface=ISP2 action=masquerade

/ip route

add check-gateway=ping disabled=no distance=1 dst-address=0.0.0.0/0 gateway=ISP1 routing-mark=TO_LINE1 scope=30 target-scope=10

/ip dns

allow remote request is yes and servers i put one dns of ISP1 and one dns of ISP2


i think i have problems with the dns

anyone can help ?

ANYONE ?

where are the experts of mikrotik?

Your mange part is not correct.
All your mark-routing rules should have passthrough=no, so packets are not processed any more.

Also, when you mark packets with in interface=Public Interface (ISP1 and ISP2) you should use chain=input.
These two rules make possible that the connections of router itself come and go via the same interface.

As for the DNS you better use public dns servers rather than ISP DNS Servers. That is because ISP may block
DNS requests from IP that are not of their own.

You should have a mangle rule set like this:

Do I need PCC if I have 2 two PPPoE links from the same provider - same gateway...

I know that PCC keeps connections but if the gateway is same?

tnx

Yes, you will still need the PCC configuration. That is because nowadays servers do require
not only username and password for authentication, but they do also look at the IP the request
is coming from, so a change in the IP would brake the connection with the servers.
